My wife has a 7mm overbit and slightlyl produding two front teeth,she does not have large gaps or crooked teeth, she visited the local Orthodontic practice, paid £150 and was advised to have Ceramic Braces top and bottom for £3000, with two upper extractions(one an old Crown). Invisilgn was ruled out as less effective.She visited her Dentist to have the extraction and was advised they could fit a Brace (Inman Aligner??)top and bottom, no extraction but file the teeth giving an almost as good a result in 4 months, £2400, she did not have extractions as she needed to think.Neither practice provides the treatment the other does and neither mentioned a lingual Brace (ingognito?). We now do not know what to do. She is slightly worried about the conspiciousness of the Ceramic train tracks, particularly on the bottom,but if the Inman aligner is less effective then why not opt for Invisilign, alternatively is an Incognito Lingual brace going to cost more than the £3000 for ceramic train tracks, we may have to pay another £150 just to find out!! Any advice more than welcome.
